Sonic Forces, known as Project Sonic 2017 during development, is a video game set to release in late 2017. In the same vein as Sonic Generations, the game features both the "classic" and "modern" forms of Sonic the Hedgehog. Additionally, it introduces a new gameplay style in which the player creates an avatar, known as a "Custom Hero". Forces is the first game to use the Hedgehog Engine 2 as its rendering engine.
